Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.

Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.

Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.

So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.

Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.

And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.
